Patent DE-3831098-A1 (DE)
Title: Active ingredient for a composition for decolorising, stripping off-shade dyeings and weakening the shade of dyed textiles
Inventor: PLACK LUDWIG
IPC: D06L4/30
Filed: 1988-09-13
Abstract: The invention relates to a combination of active ingredients for a composition for decolorising, stripping off-shade dyeings and weakening the shade of dyed textiles. It contains thiourea dioxide and consists of two components which are each free-flowing powders which are kept packed separately in one container until required for use and - immediately before use - are conjointly transferred into an aqueous solution to form a liquor. One of the components forms the thiourea dioxide, while the other component consists of an amount - in a certain mixing ratio with the amount of the thiourea dioxide - of a substance which gives an alkaline reaction in aqueous solution.

Title: Device for entering cursor positions
Inventor: HESS HARTMUT DR ING
IPC: G06F3/033
Filed: 1988-09-23
Abstract: The device for entering cursor positions into a computer has a base plate (10), on which contacts or infra-red transmitters (54, 56) and infra-red receivers (62, 64) are arranged. Direction sliders (70, 72), which can be slid in grooves (28, 30) between the infra-red transmitters and the infra-red receivers, are arranged above the base plate. The direction sliders (70, 72) are moved using an operating cap (90).

Patent DE-3832745-A1 (DE)
Title: Exhaust emission control device for internal combustion engines
Inventor: NYLANDER OLLI DIPL ING
IPC: F01N3/021
Filed: 1988-09-27
Abstract: Nowadays the exhaust gases of internal combustion engines are often treated by catalytic processes or filtered. Neither process is ideal.   In the process according to the present patent application the exhaust gases are made to flow through a vessel, in which they come in contact with a neutralising and filtering substance. The vessel gives rise to counter-pressure. In order to compensate for the said counter-pressure, a turbo compressor, which functions so that the exhaust gases first flow through the turbine and then through the compressor, is incorporated into the exhaust pipe system downstream of the engine. For the present patent application an axial flow turbo compressor is shown, but in practice it is possible to use a radial flow turbo compressor. When controlling exhaust emissions by this method turbocharging must be dispensed with or a double system fitted. A portion of the exhaust gas energy is then used to supercharge the engine, the other portion for the exhaust emission control.

Abstract: A rectangular packaging container having a top part and a bottom part has an upright edge piece on two opposite sides of the top part, at least one edge section on a third side of the top part, and a free opening on the side of the top part opposite the third side. Formed in the mutually opposite edge pieces on the first and second sides is in each case at least one resilient catch lug which projects into the interior of the container and can be displaced outwards by pressure from above and has a predetermined spacing from the inner face of the top part. Formed in the bottom part having an outwardly projecting edge is at least one pocket which is essentially adapted in its dimensions to an article to be packaged. The top part is fitted by pressure onto the bottom part in the vertical direction, the catch lugs of the top part engaging in a clamping manner in the outwardly projecting edges of the bottom part which can be released from the top part by a sliding movement to remove an article, whereupon the packaging container can be closed again by pressing the top part onto the bottom part.

Title: Car battery safeguard - using plate of specified plastic material with fibre reinforcement to prevent theft
Inventor: BAUR WILHELM
IPC: H01M50/227
Filed: 1989-05-19
Abstract: Surface hardened steel plates are at present fitted to car accumulators to prevent the drilling of a hole in the battery casing by a thief so that all electrical anti-theft protection devices become inoperative.

Title: Image motor transfer - using laser copier and fixing oil
Inventor: GRUENINGER MANFRED
IPC: G03G7/00
Filed: 1989-05-26
Abstract: A pictorial motif on a carrier (3) for example, to be attached to a T-shirt (4) is produced by placing a master copy (1) in a laser copier (2) which produces on the carrier (3) an image by exposure and scanning with an image converter with filters for the basic colours, red, green and blue. Three different toners are used to transfer a see-through foil. The toner picture is fixed by fixing oil (dimethyl polysiloxane). The picture is transferred from the motif carrier to the image carrier (4) by a conventional technique. A three-dimensional motif can be obtd. by placing the motif carrier in a frame which is filled with a casting cpd. contg.  a colour solvent. This compound can be PVC, PU, PU foam, PE, PP, polycarbonate, alkyd resin or PM. ADVANTAGE - This simplifies the transfer of fast and sharply contoured images.

Title: Procedure and plant for disposal of refuse dump gas and seepage water - gas is burnt and seepage water cleaned by reverse osmosis
IPC: B01D53/34
Filed: 1989-12-15
Abstract: Procedure for disposing of gas and seepage water from refuse tips is proposed. The gas evolved is conveyed to a muffle oven (2) in which it is burnt at such a temp. as to destroy all of its components which may be damaging to the environment and the flue gas from this oven is used as part of the heat input to a steam boiler (3) before being exhausted through a chimney stack.  The steam produced in the boile is used to drive a steam engine or turbine (6) , and is then condensed in an evaporator (9) and dryer (19) before being d to the boiler. The steam engine or turbine being used to supply electrical energy to the seepage water treatment plant. The seepage water is cleaned by reverse osmosis (13), and the concentrate from the reverse osmosis process is further de-watered in the evaporator described above, the water recovered being recirculated to the seepage water inlet point (32). The steam is generated in the evaporator is cleaned, and the concentrate from the evaporator is dried in a dryer and then dumped, the moisture from the dryer also being condensed and recirculated to the seepage water inlet point (32). The steam from the evaporator (9) may be passed through a stripping column, (14) to remove volatile impurities the condensate from the column being returned to the seepage water inlet point and the concentrate taken to a scrubber (17) from which the solids are dumped and the liquid residue is recirculated to the dryer.  Sulphuric acid may be used to produce an exothermic reaction in the scrubber (17), the reverse osmosis and stripping processes may have more than one stage. Water is passed in contra-flow through the scrubber (17) and is subsequently partly condensed in the stripper to reduce ammonia concn. USE/ADVANTAGE - The system and a plant arrangement are used for disposal of gas and seepage water from rubbish  dumps in which the gas is burnt and the water is cleaned by reverse osmosis.

Patent DE-4007947-A1 (DE)
Title: Laser-beam working - using additional energy source to maintain plasma energy coupling capability during time in cycle when main laser beam is switched off
Inventor: BEYER ECKHARD DR ING
IPC: B23K26/00
Filed: 1990-03-13
Abstract: Method of working a workpiece with a laser beam consists of directing the laser beam onto the workpiece for a short time (T1) with an intensity (1b) which is above the lower level (Ic) at which a surface plasma is produced but below an upper level (Id) at which a laser beam induced detonation wave is produced. The beam is cyclically broken and replaced during the non-working stage by a second energy beam. The duration of the second beam is much longer than that of the first beam which built the plasma and has an intensity (IL2) which avoids any beam induced detonation waves. After a predetermined time (Tr) the first beam is renewed for the required time (T1). ADVANTAGE - The second energy beam ensures that the plasma is not fully extinguished and retains an energy coupling through it. This unbroken energy coupling increases the coupling rate of the energy over the working time thereby increasing the working efficiency without fear of detonation waves.
